What is the hidden power type on sylveon? Best nature would be calm (for a special defensive tank) or modest (hard hitter). Best ev spread is 252 sp atk and sp def. final 4ev in hp I guess. If you want more bulk but less power then 252 hp and 4 ev sp atk. Don’t think rocky helmet is the best item. Maybe leftovers

Latios moveset is ok. But it can definitely improve. Dragon pulse for dragon stab for starters. Get rid of surf. Timid nature is preferable. Calm is ok but better suited its counterpart latias. I would go 252ev sp atk and speed. 4ev sp def

Volcarona is good but that nature is awful. Timid or modest. Either more speed or more power. 252 ev sp atk and speed. 4ev sp def

Marshadow is pretty much perfect. 252 ev attack and speed. 4ev hp I guess.

Crobat is also pretty good but fly isn’t a good move. I suggest replacing it with a different flying stab move. Or flynium z instead of black sludge. Go the same ev spread as Marshadow

For weavile replace metal claw with knock off. Same ev spread as marshadow again

Overall a fairly good team. Only thing is that you don’t have a dedicated tank or wall
